Michigan Manual Flashcards
How is epinephrine-induced digital ischemia treated?
Phentolamine
Wavelength for pulse dye laser and indication
585-595 and vascular lesions
Indication for q switched lasers
Tattoo removal
Topical treatments for BCC
Imiquimod (5-6 weeks) or 5FU (3-6 weeks)
Palisading nuclei on histology
BCC
Most common type of melanoma
Superficial spreading
Most aggressive melanoma type
Nodular
Least aggressive melanoma type
Lentigo maligna melanoma
Most common melanoma type in POC
Acral lentiginous melanoma (in palms, soles, and subungual)
Histological changes in skin after tissue expansion
Epidermis increases in thickness through hyperkeratosis and acanthosis
Reticular dermis thins, no change in papillary dermis
Where to place incisions related to expanders
Radial to expander pocket, perpendicular to direction of expansion
Three unique properties of laser light
Monochromaticity (single wavelength or narrow band of wavelengths)
Coherence - in phase temporally and spatially
Collimation - travel in parallel without spreading even over long distances
Co2 laser wavelength
10,600
Erbium laser wavelength
2940
Wavelength for pulse dye laser
585 or 595
